Abstract
An improved medical holmium laser therapy apparatus belongs to the area of medical implement technology. The technical problem needs resolving is that: to supply a kind of medical holmium laser therapy apparatus that can raise the opto-electrical slew rate, has low power dissipation and high treating speed. The main technical points are that basing on the existing holmium laser therapy apparatus, holmium laser photo spot cavity (24) of the holmium optical master (2) is of elliptic cylinder shape and the cavity is made of vesicant model polyfluoroethylene which can stand fire in the ingot cavity (20); the rear cavascope of the laser cavity resonator (21) is concave holophote and the previous cavascope (25) is plano-convex holophote. The transform of the photo spot cavity makes the xenon lanmp in the cavity achieve real ray diffused reflection and irradiating evenly to the holmium bar raises the electrical-opto slew rate and the delivered power; the improvement of the syntonic lens structure in the syntonic cavity increases the speed and the effection of treatment; the performance of the complete appliance is stable, safe-guarded and prominent healing effect.
Description
Technical field: this utility model relates to a kind of laser therapy machinery, particularly a kind of improved medical holmium laser therapy machine.
Background technology: Chinese patent CN02257826.9 discloses a kind of medical holmium laser therapy machine, the conduction velocity that this machine utilizes holmium laser to have in tissue reaches very easily by the characteristics of the very fast absorption of biological tissue than the fast hundred times of conventional laser, the physical characteristic faster several times than conduction of heat, successfully holmium laser is used for to the body foci burn, solidify, Wicresofts such as vaporization, cutting hinder or the atraumatic surgical treatment, thereby filled up the blank of domestic holmium laser therapy.But, because the design of the holmium laser-gathering cavity resonant cavity of this machine is reasonable inadequately, cause its light-photoelectric transformation efficiency low, power consumption is big, and treatment speed is slower.
Summary of the invention: technical problem to be solved in the utility model is: be intended to overcome the deficiency of above-mentioned prior art, provide a kind of and can improve light-photoelectric transformation efficiency, little, the improved faster medical holmium laser therapy machine of treatment speed of power consumption.Its technical scheme is: a kind of improved medical holmium laser therapy machine, comprise holmium laser, Laser Power Devices, refrigeration system, control and liquid crystal display systems, it is characterized in that: the holmium laser-gathering cavity in the described holmium laser is the laser pump cavity of oval column, is made by the high temperature resistant polyene fluorothene of the expansion type that is arranged on the ingot bar intracavity; The Effect of Back-Cavity Mirror of laserresonator is a concave mirror, and front cavity mirror is the plano-convex total reflective mirror.Compare with original technology, its technique effect is: owing to change the holmium laser-gathering cavity into interior cylindrical laser pump cavity that the high temperature resistant polyene fluorothene of expansion type is made by copper laser pump cavity, thereby make the light that xenon lamp sends in the laser pump cavity really realize diffuse-reflectance, to the irradiation of holmium rod evenly, not only electricity-light conversion efficiency has improved 50% by 1.5%, and peak power output is also brought up to 34W by 18W, Overall Power Consumption then drops to 3W by 5W, the temperature of laser operation is also brought up to 20 ℃-25 ℃ room temperature running down by 3 ℃-8 ℃ low temperature, start need not to wait for the work that gets final product; Simultaneously, by improvement to laserresonator resonance lens structure, laser single-pulse energy is brought up to more than the 3.5J from 1.5J, treatment speed and effect have not only greatly been improved, and laser pulse width also increases to alternative pair of pulsewidth output by original single pulsewidth (250us), as can use broad pulse (600us) when cutting and organizing, and can use burst pulse (300us) during rubble, thus the dual-use function of real realization the " efficient lithotrite " and " precise laser cutter "; In addition, complete machine detects and clinical use through State Food and Drug Administration, and its stable performance is safe and reliable, evident in efficacy.
Attached explanation:
Fig. 1 is this utility model structural representation;
Fig. 2 is the holmium laser structural representation;
Fig. 3 is a laser pump cavity shape sketch map.
The specific embodiment:
As shown in Figure 1, this machine is made up of holmium laser 2, Laser Power Devices 3, refrigeration system 4, control and liquid crystal display systems 5.Holmium laser-gathering cavity 24 (see figure 3)s in holmium laser 2 (see figure 2)s are the laser pump cavity of oval column, and laser pump cavity is made by the high temperature resistant polyene fluorothene of the expansion type that is arranged on ingot bar 20 intracavity.Place holmium rod 22 and the xenon lamp 23 that is connected with Laser Power Devices 3 in the laser pump cavity.The Effect of Back-Cavity Mirror 21 of laserresonator is a concave mirror, and front cavity mirror 25 is the plano-convex total reflective mirror.Output Laser Power Devices 3, light xenon lamp, the columned laser pump cavity diffuse-reflectance that the light that xenon lamp produces is made via the high temperature resistant polyene fluorothene of expansion type evenly gathers on the holmium rod, form population inversion, produce excited radiation light, after the Effect of Back-Cavity Mirror 21 and the round vibration amplification between the front cavity mirror 25 by laserresonator, from front cavity mirror output holmium laser, focus on the optical fiber 6 through coupling mirror 28, transfer to biological pathological tissues through the light pricker again, can burn it, solidify, Wicresofts such as vaporization, cutting hinder or the atraumatic surgical treatment.
Before holmium laser is treated focus, people's internal lesions position determined that be provided with the windows 26 of 45 degree between front cavity mirror 25 and coupling mirror 28, the below of window is provided with the display lamp 27 of green in order to cooperate endoscope.
